Viscosity Meters

Product Details:

Krebs Viscometer from Rhopoint Instruments offers high accuracy viscosity measurement with advanced functionality.

Viscosity measurement of coatings is essential at each stage of the manufacturing process to ensure consistent quality standards.

Many parameters can affect the rheological behaviour of a finished coating resulting in undesirable affects such as sagging, levelling, brushability and atomisation. The use of high precision measuring instruments is therefore essential in quality control to prevent such problems occurring during formulation, manufacture and application.

Product Details:

Cone and Plate Viscometer provides high accuracy viscosity measurement of non-newtonian paints and coatings. This Viscometer is specifically designed to provide stringent testing conditions to allow the measurement of these materials as the viscosity changes according to the shear stress that is applied. A precision wear resistant cone rotating at high speed on a temperature controlled plate produces standardised shear rates during measurement. Fully automated operation ensures rapid and accurate positioning of the cone onto the plate each time after the plate temperature has reached its preset value. Results are displayed instantly on screen after test.. Real-time high resolution graphing provides monitoring of changes in viscosity during measurement allowing the identification of changes in flow behaviour.
